Threaded Sealing Caps - UNF Threads
In stock
These Threaded Sealing Caps for UNF Threads protect threads and fittings from damage during production, storage, and shipment, ensuring that they remain in good condition and ready for use when needed. The cap is fitted with an internal neoprene rubber sealing disk to limit fluid leakage, plus it reduces potential shearing. The protection plug protects from contaminants like dirt, dust, debris, and moisture from the hole.
It is easy to install and remove by hand, but its hex head allows the plug to be applied or removed with a spanner or socket at low torque. Used in various applications, including hydraulic, pneumatic and general engineering industries.
